Fish are losing their survival instinct - even becoming attracted to the smell of their predators - as the world's oceans become more acidic because of climate change, new research said Monday. The study of fish in coral reefs off the coast of Papua New Guinea - where the waters are naturally acidic - showed the animals' behaviour became riskier. "Fish will normally avoid the smell of a predator, that makes perfect sense," lead author Professor Philip Munday from Australia's James Cook University told AFP.
